事务隔离：当前事务和其它事务的隔离的程度。例如，这个事务能否看到其他事务未提交的写数据？
Isolation: the degree of isolation this transaction has from the work of other transactions. For example, can this transaction see uncommitted writes from other transactions?
没有适当的事务隔离性，其他工作单元就可以访问某一活动工作单元所做的更新，即使该工作单元还未完成。
Without proper transaction isolation, other units of work can access updates made by an ongoing unit of work, even though that unit of work is incomplete.
isolation：JPA 1.0不支持自定义隔离级别，因此开发人员需要指定数据库端的默认事务隔离级别。
Isolation: JPA 1.0 doesn't support custom isolation levels, so developers are required to specify the default transaction isolation level on the database side.
因为EJB的事务隔离级别是在部署描述符中设置的，所以具有不同事务隔离级别的不同应用程序可以重用同一个EJB。
Because the EJB's transaction isolation level is set in its deployment descriptor, the same EJB could be reused in different applications with different transaction isolation levels.
在这种情况下，改变EIS代理的事务隔离设置，可能不会有什么区别，因为ECI和XCF通信协议不会把该信息传递到后端。
In this case, changing transaction isolation Settings for EIS facades will make little difference, as the ECI and XCF communication protocols will not communicate this information to the back ends.
遵循为数据源引用设置事务隔离级别中的步骤将事务隔离级别更改为REPEATABLE_READ，然后再次运行该应用程序。
Follow the steps in transaction isolation level setting for a data source reference to change the transaction isolation level to REPEATABLE_READ, and run the application again.
更改发生在数据库上，所以WebSphere不知道已经发生了更改，而且在下一次从池中检索连接时可能无法重置事务隔离级别。
The change happens on the database, so WebSphere is not aware that it changed and might not reset the transaction isolation level the next time the connection is retrieved from the pool.
要让应用程序工作，只需用REPEATABLE_READ事务隔离级别来配置CustomerBMPEJB的数据源引用。
To make the application work, simply configure the data source reference of Customer BMP EJB with the REPEATABLE_READ transaction isolation level.
数据库管理员可以使用OPMEE提供的域专家功能进一步研究这些事务以隔离问题。
A database administrator can further investigate these transactions to isolate the problem using of the domain expert capabilities that OPM EE offers.
此时，数据库管理员可以使用OPMEE提供的领域专家功能从这里开始进一步研究这些事务以隔离问题。
At this point, a database administrator can further investigate these transactions to isolate the problem using of the domain expert capabilities that OPM EE offers.
确定这是否适合您的需要，还要考虑您为事务定义的范围(和隔离级别)将如何影响整体并发需求。
Determine if this is appropriate for your needs, and also consider how the scope (and isolation level) you define for your transactions can impact overall concurrency requirements.
如果对一个帐户同时处理多个请求，则必须隔离这些请求，以便一次只能有一个事务影响该帐户。
If multiple requests are processed against an account at the same time, they must be isolated so that only a single transaction can affect the account at one time.
开发了EJB后，程序员必须设置定义各种特征(如ejb的事务支持和隔离级别)的部署描述符。
After developing an EJB, the programmer must set deployment descriptors that define characteristics, such as transaction support and isolation levels for the EJB.
在参与事务中的锁超时事件前执行的所有sql语句信息，如语句文本、使用的隔离级、执行顺序等等。
Information about all SQL statements executed before the lock-timeout event in the participating transactions, such as statement text, isolation level used, order of execution, and so on.
“受信任的代码”在控制区域中运行，用户应用程序代码在服务区域中运行，从而将应用程序执行与事务管理完全隔离。
"Trusted code" runs in the control region, user application code runs in the servant region, which completely isolates application execution and transaction management.
请注意，只有您的范围在一个事务中读取全局变量，并在另一个事务中更新同一全局变量时，才需要使用范围隔离。
Please note that you need isolated scopes only if your scope reads a global variable in one transaction and updates the same global variable in another transaction.
Percolator通过“快照隔离”实现了遵从ACID的跨行及跨表事务，从而满足多线程在多台服务器上对文档库进行转换操作的需求。
Percolator was designed to provide cross-row, cross-table ACID-compliant transactions via " snapshot isolation" since many threads on many machines need to transform the repository.
低级(lower - level)技巧涉及在体系结构中尽可能低的层启动事务，同时仍然能够更新操作的原子性和隔离。
The lower-level technique involves starting the transaction at the lowest possible layer in the architecture while still being able to maintain atomicity and isolation of the update operations.
大多数语言实现都假设事务中执行的代码是单线程的，但是隔离和并发是两个互不影响的概念（Amdahl 定律将受到多核的冲击）。
Most implementations (hw or sw) assume code inside a transaction is single-threaded, but isolation and parallelism are orthogonal (and Amdahl’s Law will strike with manycore)
新的CurrentlyCommitted隔离级别在处理写者事务的同时，允许系统中的其他读者事务读取数据。
The new Currently Committed isolation level allows writer transactions to continue processing while the other reader transactions within the system get their data.
现在，我们将事务定义为对应用程序状态的相关操作的集合。 事务具有原子性、一致性、隔离性以及持久性 这几个属性。
We can now define a transaction as a related collection of operations on the application state, which has the properties of atomicity, consistency, isolation, and durability.
虽然示例中使用的资源适配器不响应J2EE事务性隔离级别设置的变化，但是某些围绕关系数据库系统构建的EIS确实可能会受到影响。
Although resource adapters used in the example do not respond to changes in J2EE transactional isolation level Settings, some EISs built around relational database systems may be affected.
一位安全人士说到，这项工程是以色列的内部事务“埃及对此无能为力，因此隔离墙是修建在以色列的领土上。”
One security source said the project was an internal Israeli matter "which Egypt has nothing to do with as long as the fence is built on Israeli soil".
这个隔离级只有当一个事务对同样的数据进行两次读操作而其他事务修改了两次读操作之间的数据，从而导致了每个读操作的结果不同时才会发生。
This happens when a transaction reads the same data twice, while another transaction modifies the data between the two reads, resulting in in a different result for each read.
当出现与可用性和响应时间有关的问题时，TransactionCollector (TC)代理和TransactionReporter (TR)代理将隔离问题并使用事务拓扑图进行诊断。
When availability or response time issue occurs, transaction Collector (TC) agent and transaction Reporter (tr) agent isolate problem and diagnose with the transaction topology diagram.
WS-AT 可以确保以事务方式执行对这三种Web服务的调用，并向应用程序提供原子性、一致性、隔离性和持久性 (ACID)语义。
WS-AT ensures that invocation of these three Web services is performed in a transactional fashion, providing Atomicity, Consistency, Isolation and Durability (ACID) semantics to the application.
在其它事物之间，不严格隔离属于不同的Web服务事务规范，这种事务规范针对大多数宽松的受控环境：Web 服务业务活动（WS-BA）。
Relaxed isolation, among other things, is the subject of a different web services transaction specification aimed at more loosely controlled environments: Web Services Business Activity (WS-BA).
中间件开发团队提供另外的性能度量，将用于主机通信、消息分析的耗用时间与用于事务处理的中间件耗用时间隔离开来。
The middleware development team provided additional performance metrics to isolate the elapsed time for host communication, message parsing, and the middleware elapsed time for transaction processing.
